Do I need any fonts to use Easy Barcode Creator?

No – Easy Barcode Creator doesn't rely on installed fonts to create barcodes.

The numbers above and below some barcodes are produced with special typefaces called OCR-A and OCR-B. These typefaces are built-in to Easy Barcode Creator. When you create a barcode in vector EPS format, the EPS file contains outlined versions of these characters, so there are no font dependencies.
